Final answer:
Black ice is a thin layer of transparent ice that forms on the road. It can be dangerous because it is difficult to see and can cause vehicles to lose traction.
Step-by-step explanation:
Black ice is a thin layer of ice covering the asphalt. It is called black ice because it is transparent, making it difficult to see on the road. This is especially dangerous because it can cause vehicles to lose traction, leading to accidents.
The term 'black ice' is used to describe ice that is formed when moisture from the air freezes on a cold surface, such as the road. It can form in areas where the temperature is below freezing, even if there is no snow or visible ice present.
Driving on black ice requires caution and special attention. It is important to slow down, increase the distance between your vehicle and the one in front of you, avoid sudden maneuvers, and use gentle braking. Having good winter tires and practicing defensive driving techniques can also help minimize the risks associated with black ice.
